GRAIN-DRILL..

SPECIFICATION forming part of Letters Patent No. 744,802, dated November 24, 1903.

Application led August 3,1903.

To a/ZZ whom, t may concern:

Be it known that I, DAVID B. SALTSMAN, a citizen of the United States, residing at the city of Dowagiac, in the county of Cass and State of Michigan, have invented certain new and useful Improvements in Grain-Drills, of which the following is a specification.

This invention relates to improvements in grain-drills.

It relates particularly to improvements in disk furrow-openers for grain-drills, although it is adapted for use in other relations.

The objects o f the invention are, first, to provide an improved disk furrow-opener for grain-drills and the like which is simple and compact in its construction and strong and d urable; second, to provide an improved disk furrow-opener for grain-drills and the like Which can be readily assembled and disassembled; third, to provide an improved bearing for disk structures of the class described which is thoroughly protected from the dirt and is at the same time readily accessible;

, fourth, to provide an improved bearing for disk structures of the class described which is easily lubricated and the lubricant retained therein.

Further objects, and objects relating' to details of construction, will deiinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following` specification.

The invention is clearly defined and pointed ont in the claims. 3

A structure embodying the features of my invention is clearly illustrated in the acco1npanying d1awings,forming a partof this speciiication, in which* Figure 1 is a side elevation View of a strueture embodying the features of my invention. Fig. 2 is an enlarged detail sectional view taken on a line corresponding to line 2 2 of Figs. l and 3 looking in the direction of the little arrows at the end of the sectionlines. Fig. 3 is an enlarged detail side elevation view of a portion of the boot, showing its structure for the attachment of the bearing; vand Fig. 4 is a plan view of oneof the bearing-blocks C looking from the outside.

parts throughout the several in position on the boot by a bolt D, whichl clamps them securely in position. Each bearing-block C is provided with an annular flange or disk-like head C.

Mounted upon each bearing-block is a bearing-plate B', having an outwardly-projecting iiange B, adapted to embrace the head ofthe iiange C of the bearing-block. The bearingplate is provided with a shoulder at b, adapted to receive the disk B, which is secured in position by suitable rivets or the like.

The outwardly-projecting flange BH of the bearingeplate projects beyond the face of the bearing-block and is provided with screwthreads to receive the screw-threaded retainin'g plate or nut E. The retaining or threaded plate E also` forms a portion of the bearing of the disk.

The bearing-blocks are provided with oilpassages consisting of notches c in the boltholes, (see Fig. 4,) so that the oil passes freely fromthe chamber a within the boot tothe bearing. The oil is delivered to the chamber a' through the oil-duct d, arrai'lged in front of the boot.

The bearing-plates B are provided with annular grooves b on their inner faces to receive the packing-rings or washers c. These Washers are preferably made of felt or other fibrous material and assist in retaining the lubricant in the bearing and also in excluding the dust and dirt therefrom. The washers as thus placed are protected from any considerable wear and are very effective in retaining the lubricant and also in excluding the dirt. With the parts thus arranged the disks arel supported in such a manner that the strain thereon is reduced to a minimum.

The bearing is very accessible, and all that it is necessary to do is to remove the threaded Toward the lower plate E, and, if desired, the disk canA be released by releasing the bearing-blocks, the one bolt D securing them in position.

. I have illustrated and described my invention as applied to double disk structures adapted for use as furrow-openers for graindrills. It is, however, evident that the same is applicable for'use in other relations.

I have illustrated and described my improved disk structure in the form preferred by me on account of its economy in construction and durability in use. I am aware, however, that it is capable of considerable structural variation without departing from my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is- Y. l. The combination of a boot; bearingblocks C having disk-like heads C/ thereon secured to said boot; oil-ducts c through said bearing blocks; an oilconduit a connected therewith; bearing plates B' having outwardly-projecting flanges B thereon mounted on said bearing-blocks; annular grooves b on the inner faces of said bearing-plates; washers of suitable iibrous material in said grooves; retaining-plates E, screw-threaded into said flanges; and disks B secured to said bearing-plates, for the purpose specified.
